layoutParams錯(cuò)誤
java.lang.ClassCastException: android.view.ViewGroup$LayoutParams cannot be cast to android.view.ViewGroup$MarginLayoutParams MarginLayoutParams lp = (MarginLayoutParams) child.getLayoutParams();這句代碼這個(gè)錯(cuò)誤，怎么回事呀？我是按照視頻里一點(diǎn)點(diǎn)敲出來(lái)的怎么會(huì)報(bào)這個(gè)錯(cuò)誤呢？
